Lot-tested · Cold-chain shipped
Peptides, supplied with the paperwork to trust them.
CL Biolabs prepares lyophilized research peptides in single-use vials, each one traceable to an independent HPLC and mass-spec report. Built for labs that check their reagents before they trust them.
Individually vialed, by compound
Every vial ships with its own lot number and matching certificate of analysis — nothing pooled, nothing re-labeled.
How a vial gets to your bench
Solid-phase synthesis
Peptides are synthesized to order and purified by preparative HPLC before lyophilization into single-use aliquots.
Independent lab testing
A third-party lab runs HPLC purity and mass-spec identity confirmation on every production lot, not a sample batch.
Cold-chain dispatch
Vials are packed with cold packs and desiccant and shipped with the COA for that specific lot attached to the order.
Third-party test reports
Research protocols
Ask before you order
Every inquiry gets a reply from someone who can read a COA, not a script. Tell us the compound, the fill size you need, and where it's headed — we'll confirm lot availability and lead time.
